GHL Doser 2.2 (GHL Dosing Pumps)

The GHL Doser 2.2 Stand Alone has integrated control electronics and works independently.

The 24 V stepper motors enable accurate dosing even at the smallest flow rates (0.1 ml). The device is conveniently operated from your smartphone or your PC. The connection is possible via WiF and USB.

The GHL Doser 2.2 is available as a stand-alone unit (SA) and as an extension unit (EXT). It includes two PAB ports for connecting additional GHL Doser 2.2 EXT, Maxi Doser EXT or KH Director devices via ProfiLux Aquatic Bus. PAB cables are not included and must be purchased.

One GHL Doser 2.2 SA can control 3 additional GHL Extension Dosers (GHL Doser 2.2 EXT or GHL Doser Maxi 2.1/2.2 EXT) and can thus be expanded to a dosing system with a total of 16 pumps.

Milliliter precision and automated dosing of liquids such as

• Fertilizers
• Trace elements
• Balling Salts
• lime water
• Liquid food
• Integrated top-up with evaporated water (Auto Top-Off)
• Water change of small water volumes

• Expandable to 16 pumps or dosing channels
• Stainless steel motor shafts (also suitable for iodine dosing)
• Chemical resistant hoses
• Manual operation of each individual pump is possible
• Pumps can be retrofitted
• Individual parts can be replaced (hoses, pump head, motor)
• 24V stepper motors enable micro doses of 0.1 ml

Up to 150 doses per day

• Simply choose dosing times via software (GHL Control Center).
• Automatic: up to 150 individual doses per day automatically distributed
• Individual: up to 8 doses per day individually set
• Each pump can be set individually
• Transport capacity and dosage:
• 8-45 ml/minute (precisely adjustable to 0.1 ml)
• Level indicator

• WiFi and USB
• Alarm function
• Large LED status indicator
• Status LED for pumps
• Easy to program via our free PC software GCC

Professional CAN bus system ensures reliable and interference-free networking of all network devices.
The LED-backlit GHL logo in the housing lid serves as a status indicator. Different colors show you the state of your system at a glance.
Each pump can be operated manually via the push buttons on the front panel. This allows you to quickly re-dose, drain the hose or suck up liquids.

Doser 2.2 pumps are largely maintenance free. For optimum performance, we recommend occasionally cleaning the pumps to remove dust and other impurities. The pumps must never be lubricated! Hoses, pumps and motors are wearing parts, the service life depends on the frequency of use, flow rate and environmental conditions. In the event of malfunctions (e.g. insufficient flow, loss of supply, leakage, increased operating noise) or mechanical damage, the parts subject to wear must be replaced. Due to the maintenance-friendly design, all wearing parts are easy to replace, all wearing parts are available as accessories.
